Should I wish my ex happy birthday?

No, I'd give him space and not prod the bear. You already described that he's having trouble moving on from your relationship and that his birthday is sort of a bad thing to him, yet you're asking if you should wish him a happy birthday? I think you need to be honest with yourself as to why you're even considering this.
It depends, a simple "Happy Birthday" is nice and lets him know you thought of him on his birthday BUT, if you want nothing to do with him anymore and are trying to move on, then no this is not a good idea because he may take it as more, especially when he still wants you.
I think you should wish him a happy birthday, it will mean a lot to him, and you will be able to make him happy for a while. Good luck!
